33's on stock rims?
I have the 4 door and am in need of some new tires so i thought it would be best to upgrade to 33's or even get a 2.5'' bb and go with 35's. My question is, can i put these bigger tires on the stock rims w/ no problems? someone told me it will mess something up with the computer in the jeep? idk thanks for ur help.

33s will work perfectly well on stock wheels. If you do a lift, you're going to want to add Spidertrax wheel spacers to prevent swaybar link interference on the inside of the wheels, but take a look at my gallery and you'll see 33s work great. Good luck, post pics when you're thorugh.

The added circumference of taller tires will throw your speedometer off and you will need to either have the dealer "flash" your on board computer to allow for the larger tires or use something like the AEV Procal to do it yourself.

There are a lot of people that post on this forum that run 33 and even 35" tires on the stock wheels without any problems with the computer. However, the issues you will face are tires that are too wide for the 7.5" wheel width. Basically, this causes uneven tire wear when the tires are aired up to spec. You can alleviate this issue by airing down a little bit from the recommended psi. This might cause an issue with the TPM sensors, but those can be reset to allow for this change in psi. The other issue you might have with 33's or 35's is rubbing due to the amount of backspacing on the stock wheels. This can be taken care of with wheel spacers that push the wheels out farther from the suspension components.

I'm also looking into my tire and wheel options as I got my hands on Rubi Unlimited springs and I'm hoping for 1-2" lift. I understand the suspension rubbing with the 12.5" width tires needing spacers or alternate offset wheels. In addition, PA is a "no tread showing from under the flares" state for inspection. So what combos work best? Stock rims + spacers? Limit to tall/skinny tires like Buckshot Mudders? 15" wheels on alternate backspacing and a 33-34" tire? What offset? Any photos of working combos?
I'm especially interested in thoughts from the PA folk that have dealt with inspection?

I got to looking at my last post and decided it was less than easy to follow.
I think an illustration is in order. This should help.

I recently put these on my 2011 unlimited sport. The only issue with the stock tim setup is that at full right turn I experience rubbing from the drivers front tire on the sway bar. Otherwise best investment yet. Actually only investment.
